Red Robin had been silently watching the scenery outside the taxi window when Lilith asked in his mind, "What did you figure out?"
"The killer has a grudge against Cain."
The leap in reasoning was too great, and Lilith did not react immediately. After a moment of silence, she asked, "Why?"
"A very simple logic problem... Oh, right, I forgot you're a demon. You probably don't read the Bible. The offering Abel gave to God was the fat from the sheep he tended, and God was pleased by it."
"If the victim had been human, I would have thought this was the work of a serial killer using Bible stories as a theme. But that man was a vampire, one of Crimson Queen Mary's subordinates, and Crimson Queen's master is Cain."
"That's why I left immediately. I knew Crimson Queen Mary wouldn't ignore the death of one of her subordinates. Mary would soon go there to investigate. That foolish woman wouldn't understand what she was seeing, and she'd recount the scene to her master—she might even bring her master there."
"Cain witnessed with his own eyes how God's favored younger son slaughtered a lamb, took the fat from its belly, and gained even more favor through that offering. This scene would definitely provoke him. So tell me, whose head do you think he'd vent his anger on?"
"...Mary?" Lilith guessed.
"You're not entirely stupid." Red Robin's tone was so calm that Lilith could not even find a reason to get angry at him.
Red Robin sighed softly and took the small display from his pocket again. The moment the screen lit up, Cain's gloomy face appeared in its center.
The camera had been positioned directly above the corpse, making every expression on Cain's face as he stared at it plainly
